fat, anti-cancer diet, etc.

Lycopene – the component due to which the tomato
becomes red. Accordingly, the “redder” the tomato,
the more of this substance in it. This trace element has similar
with beta-carotene properties (found in carrots),

It is recommended for people diagnosed with osteoporosis,
menopause or brittle bones. Lycopene reduces the risk of developing
certain types of cancer, such as cancer of the prostate, stomach, urinary
bladder and uterus. It is found in fresh tomatoes, but especially
there is a lot of it in tomatoes that have undergone heat treatment, since
the cooking process helps to release lycopene and improve its absorption
in organism[18,19].

– has the properties of a powerful antioxidant, helps to get rid of
free radicals that provoke many diseases. Big
the amount of glutathione is found in the skins of many vegetables, therefore
Tomatoes are also useful in raw form, in salads. This is very

Scientific studies have shown that tomato and tomato sauce helps
reduce the risk of prostate cancer. This effect is observed
due to the antioxidant properties of tomato. It is assumed that
lycopene and glutathione are attached to the tissues of the prostate and thus
reduce the risk of damage to her DNA.

Tomatoes are rich
for potassium. This trace element takes part in the exchange of fluids
in the body, and is also responsible for the health of the nervous system, heart
and muscles. There is a lot of potassium, like calcium, in tomatoes. Thanks to
the presence of water and many minerals, tomato is recommended as a remedy
to restore the normal amount of fluids in the body
with dehydration.

And a vitamin
C are considered essential ingredients to aid in cleansing
organism – and it is them that the tomato is rich in. Vitamin A, first discovered
in 1913, helps in the process of cell growth, strengthens the immune
system and is indispensable for the eyes. Vitamin C is a powerful antioxidant,
as it participates in the process of freeing yourself from free radicals,
and not only those who come from outside, but also those who
the body produces on its own. It has been proven that this vitamin

like fibromyalgia and multiple sclerosis..

studies have shown that lycopene reduces cholesterol oxidation
and reduces the risk of heart disease. There are even some
evidence that lycopene may reduce the risk of cataracts
and sunburn.

But, despite all these extraordinary properties, there is one
problem. To isolate it from tomato, a reduction
model. New drugs containing lycopene appear on the market
at an exorbitant price. At the same time, there is evidence that

Ripening stages of tomato

In oriental medicine

In traditional oriental medicine, tomato has a special meaning.
because it can be used both as a fruit and as a vegetable. One
from ancient Chinese books on nutrition, the tomato is described as
«sweet and sour in taste, cold in nature».

how it cools the body and reduces “liver heat”, thereby maintaining
balancing it and removing toxins. Therefore, the tomato is indispensable in the following

  • for those who suffer from decreased appetite or indigestion,
    a feeling of full stomach, abdominal discomfort
    or constipation.
    Cooked tomato is especially good for children with poor appetite;
  • for people who drink alcohol. Tomato juice drunk before, during
    time or after drinking alcohol helps the liver to metabolize it
    and quickly eliminate toxins from the liver and the body as a whole;
  • the tomato is “cold” by nature, so it has never been
    useful on hot days and in summer. Chinese medicine has an idea
    about the body and nature as one indissoluble whole, therefore
    in heat, the body will especially suffer from external heat. Heat
    causes changes in the body and can lead to these symptoms
    like dry skin, thirst, dark urine, sweat, overheating of the body, fickleness
    emotions and insomnia. The cooling qualities of tomatoes help to loosen
    these symptoms and avoid heatstroke. Tomato – summer fruit
    and is especially suitable for consumption during the hot season..

In scientific research

Despite the abundance of modern plant species and already studied
data on the beneficial properties of tomatoes, scientists continue to research
many aspects regarding tomato. So, for example, a lot of attention
is given to artificial cultivation and genetic engineering to improve
taste properties of the plant, its resistance, the presence of useful
substances, growth rate, aroma.

In addition, it should be noted that the tomato, as one of the most common
products in the domestic diet, often becomes the object of research
in economics, dietetics, innovative science, agricultural sciences.
For example, when analyzing the diversification of rural production, the cultivation of
tomatoes are considered as one of the promising branches of agricultural
farms. It is expected that the development of this industry has the potential
can bring high income, tax benefits, lack of
competition in the domestic market and a good harvest for
years when growing tomatoes in a greenhouse..

Tomatoes are also mentioned in interdisciplinary research – for example,
in the work on the images of plants in the paintings of artists as a resource of information
on the history of agronomy. This study provides an example of paintings
L. E. Melendez (1772) and P. Lacroix (1864), which show how

and antibacterial effect, improve metabolism and digestion, help

a remedy for diseases of the kidneys and bladder..

and lemon.
Salts of organic acids in the process of assimilation are left in the body
a significant supply of alkaline mineral components and thus
contribute to the alkalization of the body and the prevention of acid
shifts. Thus, tomatoes support the necessary
acid-base balance. Low purine content in tomatoes
is an important link in the structure of purine-free nutrition for prevention

all at once, and after ripening the plant dies.

Perennial tomato Is a climbing plant that
requires support with stakes or a cage. Such a tomato will be

How to determine nitrates in tomato

Selection and storage

Ripe tomatoes have a fairly rich aroma. If the smell
no, the tomatoes were most likely harvested unripe. The peduncle must
be small. When choosing tomatoes, you need to pay attention to
smoothness of the skin, no cracks, spots or bumps..

Fully ripe tomato is soft and springy, but stop on it
your choice is possible only if it is immediately used.
An overripe tomato is always good for sauces and soups. Healthy
the fruit is thin, and the flesh is uniform.

If white thin streaks are visible in the pulp, white
spots in the core, and he himself is “plastic” to the touch – which means that
tomato has nitrates..

The storage conditions of a tomato directly depend on how much
ripe. Room temperature will speed up the ripening process. Therefore,
if you want the tomato to ripen, feel free to leave it warm.
Ripe tomatoes are best stored at around 12 degrees
Celsius. At this temperature, the tomato will stop ripening, but
and will not lose its taste and useful properties..
